摘 要: 提出了一种第一段无泵浦、第二段前向泵浦和第三段后向泵浦的三段级联掺铒光纤超荧光光纤光源的新结构.数值分析了泵浦光波长、铒光纤长度以及泵浦比例对新结构性能的影响.结果表明可以找到一组适合制作成本低廉、输出功率高、谱平坦的长波段掺铒光纤超荧光光源. A new three-stage L-band erbium-doped superfluorescent fiber source (Er-SFS) is introduced, The structure utilizes the first-stage none-pumping, the second-stage forward-pumping and the third-stage backward-pumping. The influence of the pump wavelength, the length of erbium doped fiber (EDF) and the pumping ratio to the Er-SFS characteristics are studied numerically. Finally,a set of optimal parameters to simultaneously achieve a higher output power, lower ripple and lower cost as compared to the conventional L-band Er-SFS is given.
